Wire, round, rod, Copper Chromium Zirconium 2.1293 - CuCrZr - C18150

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a wire, a circle, bars, which are made of the alloy CuCrZr (C18150, 2.1293). The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

The alloy of copper with chromium and zirconium of the brand CuCrZr (other names — C18150, 2.1293) is an alloy with high electrical conductivity, hardness and ductility, moderate strength and excellent resistance to softening at elevated temperatures. The addition of 0.1% zirconium and 1.0% chromium to copper allows the alloy to be efficiently heat treated, after which the material can be plastic deformed to the desired degree of hardening.

The heating temperature of the alloy CuCrZr (C18150, 2.1293) usually exceeds 500 ° C. There is evidence that the use of this alloy contributes to a decrease in the friction coefficient of sliding in mechanical systems.

Urgency of application

Typical use of copper alloy with chromium and zirconium grade CuCrZr (C18150, 2.1293): electrotechnical industry (welding electrodes of machines for resistance welding, switches), consumer goods (rod extensions, mechanical pencil cases, light soldering tools), general metalworking (welding disks, tips and extensions for joints and spot welding).

Chemical composition

In addition to copper, the composition of the alloy in question includes zirconium (0.05… 0.25%), chromium (0.5… 1.5%), titanium (no more than 0.3%). In the composition of copper, traces of silver are allowed.
